' Application mea :une 2e, 1925. semi No. 39,752.

This invention relates generically to vphotographic c`op ing machlnes, and the pri-v mary object t ereof is to provide a photographlc copying machine in which the holder or'the sensitized sheet may be conveniently reversed to both sides o the sheet.

of the invention to provide a copy-holder ermit exp osures to be made on Itis also the purpose on the' outside of the machine to hold the ob'- ject to be photographed, and to so co-relate the copy-holder that when it is reversed the sensitized plate holder will `be reversed to bring one of the faces of the sensitized plate in line wit-h an object projecting apparatus such as acame'ra or the like.

The invention is illustrated as a duplex loying twoprojecting copying machine emp apparatuses or camera arrangedin horizontal alignment, there being .a sensitized-sheet holder pivoted within the casing of the machine between the two cameras so that the holder .may be swung 4into alternate alignment with the respective cameras, and 1n order to effect ythe operation of the holder.

I use a'reversible copy-holder outside of the machine pivoted in vertical alignment with 1 the space between the two cameras so that the copy-holder may be brought into vertical alignment with either of the cameras to 3 present the obj ect to be photographed on the proper side of the sensitized sheet.A Such machilies vare employed fo r. copying page after page of a book, and since the pages of books are usually printed on both sides, it is desirable to synchronize the movement of the sensitized plate holder with reversing movement "of the copy-holder, so

chronizin'g mechanism be holder and the sheet-holder,

I have provided synltween the copyso co-related with the copy-holder and the sheet-holder that one will partake of the-movement of the other.

The specific` const ru ction of the embodiment ofmy invention selected for illustration will be s ifc`lly described hereinafter,

lreference drawings, in whichg Fi 1 is a perspec' 'c copying mach so co ance with -my invention.

Fig. 3 is an enlar mg had to the accompanying tive view of a photoine constructed in ac-v longitudinal, sectional view through the same, and

the sensitized-sheet older. Referring now to th drawngsby numerchine. On, the front face or perspective View of'v als-'of reference, 1 designates the casing or housing' of the Iphotographic ,copying mapanel2 of the housing or casing, 'are two object projecting apparatuses 3 .and 4 shown as cameras of ap- 60 propriate construction.` These are provided with the Ausual lenses 5 and 6, andthe usual appurtenances common to cameras. The bellows 7 and 8 align with Windows or openf ings 9 and 10 i-n the front panel 2 so that 65` the objects to be photographed can be pro-4 jected upon a'sensitized sheet supported byL I n a holder 11 within the casing 1, so mounted `thatit may beA reversible to align first .with

the window 9` and then with the window 10 70 vto permit both sides of the sensitized sheet 10 to be exposed to the projecting apparatuses.I The sensitized-"sheet holder is shown as comprising a substantially rectangular frame in the top of which is a housing 12 to 75 receive a spool 13 on which astrip 14 of sensitized paper, cloth lor the like may be wound. The-sheet may Vpass over the idler roller 15 between the members 16 and 17 of a mask to 'a cutting apparatus 18 so' that-the sheet orv 8,0 i

strip may be severed at the proper time. In so` far as this invention is concerned, however, the particular construction of the sheet-holder 'is unimportant, it being obvious I that instead of feeding the sheets from a strip that' `the separate sheets can -be introduced into the sheetholder Vfor each double exposure, so I deem it unnecessary to' elaborate in this description upon the particular construction of the sheet-holder per se. Inf line with the space between the two openings 9 and 10/withi1al the casing 1 isia bracket 19 having a Vertical bearing 19 in which 'is rotatably mounted'a spindle 20 fast to one corner of the frame 11. The spindle projects through the bearing and carries atl its free end a .mitre gearj21vwhich meshes 23 projects through the front panel 2 ofthe casing. The projecting end carries a mitre gear 26 meshing with a like gear 27 on the vertical shaft 28 mounted in the bearings 29 and 30 on the front panel 2 ofthe casing' 1. The shaft 28 is provided with a groove 31 4.engaged by a projection or a key on the `huh of the gear 32 wihch is slidable, on the shaft 28. The gear 32 meshes with a gear 33 on athe shaft 34 in bearings 3 5 and 3 6 carried by 11.

the table 37. The table is adjustable vertically on the frame 37 so that the copy-holder 38, rigidly secured at one edge to the shaft 34, may be focused with respect to the cameras 3 and 4. The'copy-holder may also be moved back and forth so that it will align with the prism or lens when the camera is focused.

It will be obvious that the shaft 34 is in vertical alignment with the space between the two cameras 3 and 4. Consequently, when the copy-holder is swung toone side of its pivot or shaft 34 it will align with the lens of the'camera 3, and when swung to the opposite side it will align with the camera 4. Since the copy-holder 38 will rock the shaft 34, 180cJ when it as shownin Fig. l, the shaft 28 will be tially rota-ted through the same are, like motion being communicated to the shaft E23 so that the spindle-19 will be rotated through an arc of 180, swinging the sensitized-sheet par- Y holder 11 through an are of 180, or from one window 'to the other, that is, if the sheetholder is opposite window 9 when the copyholder is in the position shown in Fig. 1, it will be in line with the window 10 when the copy-holder is swung over upon the portion 39 of the table 37 and vice versa.

The synchronizing movements of the copyholder and the sheet-holder are due to the fact that all of the gears are of the same diameter and have the same number of teeth. The copy-holder can be constructed of two hinged members 4() and 41 with transparent panels secured together by a suitable clip 42. Therefore, if the object to be photographed is a sheet with printing on both sides, or two sheets each printed on one side only, with the plain side of one sheet opposite the plain side of the other, it will be obvious that the printed matter will be visible through both panels; and if the sheet in the holder 11 is sensitized on both faces or sides, it must follow that the objects visible through the respective panels may be photographed on opposite sides of the sensitized sheet, if an' exposure is made first on one side of the copy-holder and then on the other. Since means has been provided for synchronizing the movements of the copy-holder, liability of making two exposures on one face of the sensitized sheet will be entirely eliminated.

In this application I have not shown in detail the mechanism for vertically adjusting the table which supports the copy-holder because this may form the subject matter of a separate application, it being apparent that in so far as this application is concerned it is immaterial whether or not the cameras have fixed focuses, this particular invention residing more specifically in the synchronizing movements of the two elements, to wit, the holder for carrying the sensitized material on which the exposure is to be made, and the is swung from left to right and adapted to be moved copy-holder which carries the object to be photographed.
